While Cahokia was the capital of the Mississippi River in the 1800s, it was also a trading center that was populated by skilled tradesmen, artisans, and astronomers. It was also part of a vast trading network that stretched over North America. In addition to being located near the confluence of the Illinois, Missouri, and Mississippi rivers, the city was located in the lower lands known as the American Bottom, which were carved by glacial meltoff about 10,000 years ago.
During the American Revolution, a Virginian named George Rogers Clark captured Kaskaskia, which was then incorporated into the city. Cahokia City was then part of the British province of Quebec, but became part of the United States in 1783 when the Treaty of Paris was signed. The United States then took over the region west of the Appalachian Mountains, naming it the Northwest Territory and the Illinois Territory. At that time, 105 residents of Cahokia swore their allegiance to the Continental Congress.
Before Columbus reached the Americas, Cahokia was a civilization where humans used to build pyramids, build solar observatories, and practice human sacrifice. The settlement became abandoned after 300 years, and the earliest written references of the city were made after the French explorers missed the mounds in 1673. In the mid-1700s, French monks discovered the city and named the largest mound after them. The city was then surrounded by mystery.
